Another object is to provide a hose nozzle having an internal valve-unseating y arm which can be secured in or removed from operative position without disconnecting the nozzle from the hose or removing or disturbing the valve when functioning to shut off the flow of gasoline from the hose.

A further object is to provide simple and effective means for guarding against leakage at the point where the arm 1s secured 1n or'removed from position, and to make provision for adjustment to compensate for y wear at such point without appreciably affecting the force required to eect unseating actions of the valve.

TWith these general objects in view, the invention consists in certain novel and useful features of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which: Y p

Figure 1 is a view partly in side elevation and partly in central vertical section of a hose nozzle embodying the invention.

Figure 2 is a top plan view broken away to disclose certain parts and their relation to each other, in plan view.

Figure 3 is a vertical cross section taken substantially on the line III-III of Figure v l, and showing in dotted outline the part of a trigger shaped member vforward of the plane of the section.

Figure 4- is a detail perspective view of a valve-unseating arm.

Figure 5 is a detail side view of a fragment; of the trigger shaped member and its interlocking relation with the valve-unseatingv arm.

Referring to the drawings in detail where lilre reference charactersV identify corresponding parts, 1 indicates the body portion of the 55 nozzle, the same comprising a tubular portion preferably of obtuse angle form, and a tubular portion 3 communicating with the rear end of tubular portion 2 and extending preferably diagonally downward and rearward 50 therefrom,.the portion 3 being adapted for connection with a gasoline hose, not shown.

' The rear end of tubular portion 2 is closed by a screw plug 4, and screwed into the front end of portion 2 is the nozzle proper 5 which 65 may be of straight or other form and of any suitable length.

In substantially the plane of the junction of the forward side of tubular portion 3 with tubular portion 2, the latter is provided with a rearwardlylfacing annular valve seat- 6` andV forward thereof and axially alined therewith is a spider shaped bearing or guide 7 for the forwardly-projecting'stem of a valve composed of a head 8 and a 75 disk 9 of suitable composition material for accurately fitting vragainstthe valve seat in closing the passage thereof to the flow of gasoline.` The Vhead is provided at its rear side with a central boss 10, and a spiral spring 30 11 fits at one end over the boss and against the head and at the other end against the cap or plug 4, which is preferably hollow to permit of the use of a relatively long spring 11. The cap is not so shown as a similar cap Vis 35 employed in my Patent No. 1,695,452, issued December 18, L1928, for hose nozzles. The construction of the valve and its connection with the stem thereof is not detailed as the preferred construction corresponds to that 9o shown and described in the aforesaid patent. v`The body portion is provided with a depending guard 12 for a trigger shaped member hereinafter identified and forward of the guard with a depending hook 13 yfor use in 95 `suspending the nozzle from a gasoline pump or other convenient support, not shown.

Forward of the spider bearing, the body portion is provided with a transverse cylindrical arch portion 14 communicating with 100 the interior of the body portion and closed at one end at 15, and. provided at its opposite end with internal threads engaged by a tubular threaded plug 16, the outer or headed end of said plug being of angular form so that it may be conveniently engaged by a wrench whereby it is screwed into or out of position. Y

A valve-operating arm 17 depends vertically from the chamber of the arch portion down into the front end of lthe body portion, said arm being adapted to be swung rearwardly and apply pressure upon the front end of the valve stem to unseat the valve and permit gasoline to flow forwardly through the valve passage and nozzle. The arm 17 is' preferably provided at one side with aV short pivot pin or trunnion v18 journaled inY the socket `19 provided in the closed end of the arched portion 14. At its other side the said arm is provided with a pivot or trunnion 20 journaled in the plug 16 and of length to project slightly beyond the outer end or face of saidplug. At its outer or projecting end they trunnion 20 is of reduced diam-eter and has a series of peripheral notches 21. The outer side of the closed end of the arched portion is formed with a cylindrical boss 22 alined with the trunnion 20, and said boss and the reduced end of the trunnion 20 are 'provided as supports for the trigger shaped member hereinbeforeV mentioned. A screw bolt 23 is mounted in the closed end of the arched portion centrally of boss 22 and has an enlargement or flange 24'to bear against said boss and project beyond its periphery, and a screw bolt 25am ally Vengages the trunnion 2O and has an enlargement 26 to bear againstthe outer end of said trunnion and project beyond the periphery thereof.

A gasket 27 of any suitable compressible material fits around the trunnion 2O between the arm 17 and the inner end of screw plug 16, and means are provided for applying yielding force to hold the arm 17 clamped against the gasket so as to seal the joint therebetween and between the trunnion and said plug and thus guard against leakage through the latter. p struction the means for applying the yielding force mentioned is a coil spring 28, which bears at its opposite endsagainst the closed end of the arched portion and the opposing side of the arm 17. The same result can be accomplished by means of the trigger shaped member which comprises a lower or handle portion and an upper or forked portion. The handleportion 29 stands within the guard 12 and the forked portion comprises a pair of spaced arms 30 and 31 which are of spring metal, and have a tendency to move apart. The upper end of arm 30 is pivoted for free operation on the boss 22, and is held against dislocation .therefrom by the flange 24 of bolt 23. The other arm 31 fits over the re# In the preferred con-` duced end of trunnion 2O and is retained in such position by the flange 26 of bolt 25, and said arm 31 has inwardly-projecting teeth 32 having interlocking engagement with the notches 21 of trunnion 20, as shown by Figure 5, so that when the handle portion 29 is grasped and pulled rearwardly the member will rock and impart corresponding movement to trunnion 20 and arm 17 and thereby cause the latter to apply rearward pressure Von the valve stem and unseat the valve, the

spring 11 reacting immediately the pressure on the handle portion is released, to reseat the valve and hence restore the arm 17 and said member to normal position. In this connection it will be noted that if the forked arms of the said member tend to spring apart as suggested, this force will be transmitted by the arm 31 on the enlargement or flange 26 of bolt 25 and hence tend to cause the arm 17 to apply clamping pressure on the gasket 27.` It will thus be seen that the leakage point or points mentioned can be effectively lsealed without the use of the spring 28. It is preferred however'to use said spring even with a member having forked arms tending to spread apart in the manner mentioned. Of course a trigger shaped member may be'employed having forked arms with no substantial tendency to spread apart, and in such event the spring 28 or some equivalent will be required to insure the clamping of the gasket between the arm 17 and the plug 16.

The design of this nozzle and the leverage provided for the unseating of the valve is such that in the manipulation of the trigger shaped member there is no such reaction as tends to effect appreciable jumping7 or kicking7 action at the discharge end of the nozzle, as is true with all other gasoline nozzles of which'I have knowledge, provided with a lever operable to unseat the valve. As

' an incident of such jumping action it is a common experience around filling stations to find' considerable gasoline discharged onto the lilling tank instead of into the same. Because of this fact, many of the nozzles of otherwise approved construction require the operators to hold them in both hands in order to avoid the trouble mentioned, or else to see that the end of the nozzle is firstproperly itted into the tank opening so that the wall of the latter shall restrain or prevent the jumping or kicking motion mentioned. The necessity for using both hands to hold the nozzle is objectionable, and the ordinary filling station attendant is'frequently in such a hurry that, when holding the nozzle wholly with one hand, he does not withhold the operation of unseating the valve until he has the nozzle properly projected into the tank, and as a result there islikely to be waste of gasoline charged to ythe customer. My nozzle can be held in one hand and the valve operated so easily that there is practically no tendency for the discharge end of the nozzle to wobble or jump as stated, and for this reason the operator has little trouble in the way of splashing gasoline upon the tank,if the end oi the nozzle is in line with and close to the filling opening of the tank when the valve is unseated. Y Y

Any slight wear of the gasket 27 will be automatically taken up by` lateral shifting of the arm under the yielding force applied thereto, and take-up may also be edected by adjustment of the screw plug. To replace a defective gasket, the trigger shaped member is removed and after withdrawal of the screw plug, the arm can be entirely removed or withdrawn enough to permit the old gasket to be slipped oil the trunnion 20, and replaced by a new one. rlhe plug is then resecured in )lace and the trigger shaped member returned to operative position.

From the above description it will be apparent that l have produced a nozzle embodying the features of advantage set forth as objectives in the statement of the objects ofk the invention, and while I have illustrated the preferred construction it will be understood that various changes may be made within the spirit and scope of the appended claims.
